Model radio spectrum of a z = 1 galaxy, forming stars at a rate of ψ ≈ 25M⊙yr−1. Synchrotron, free–free, and thermal dust emission components are identified, along with the J=2→1 and J=1→0 emission lines of CO. The grayed region identifies the rest-frame bandpass of 10 GHz observations for such a source, illustrating that, at  z≳1, these data should become sensitive to free–free emission, and hence current star-formation activity in high-redshift galaxies.
